Abstract

En anordning til oppnåelse av et av ytre akustiske betingelser upåvirket frekvensforløp i høreinnretninger i kommunikasjonsterminaler benytter som elektroakustisk omformer en dipolomformer som er anordnet slik i et hus at det sikres et fritt utløp av lydbølgene fra for- og baksiden av dipolomformeren.An apparatus for obtaining an unaffected frequency loss in the hearing aids in communication terminals utilizes as an electroacoustic converter a dipole converter arranged in a housing to ensure a free discharge of the sound waves from the front and back of the dipole converter.
